Thank youHere is the fritzing schematic
Thanks for the link. Basically this is "hot plating" but with limited control over the temperature, that's why I purchased the oven. Hot plate however is preferred by others as they can make corrections while the components start to move as you can look at it which is not possible in an oven. Nevertheless I hope that most people are able to just solder the PCA9685 with a good solder iron. Since the PCB has the size of a normal PI it would be too big for the clothing iron, however there is only 1 SMD component on the middle of the board, so maybe it could work.is easy with clothing iron. if only for small size like pi Zero

I love the perma proto boards. Go with this one: https://www.amazon.com//dp/B00SK8KIGA/ it does not have the headers@Ranjib I have been playing a bit more in Fritzing. I found this SLICK board from ADAfruit on AMAZON. I might order this but I really want to build this weekend. Maybe it is ordered down the road LOL. It should have the capacity for most all in one build. Here it is added to my current sketch(cropped).
When I add the 2nd power bar, I plan to use this instead of the small Hat so it is all contained. this would be Phase 2. LOL.
This is that feeling of first tank... Its just the beginning, but still its so exciting. I'm glad you took the plunge. I myself get excited looking at other users builds (like yours) that run my software, its very fulfillingDave. I did noobs too. Formatted the card and then unzipped noobs and copied files. Lights come on. Did you hdmi to a monitor? One light comes on and other flickers like a drive read light I believe.
Btw, check out what I made. It's ugly. But I have NEVER soldered before. Ever. This is my temperature circuit. And it freaking works! I need to buy some smaller wires. My old auto wire is quite large and I had to cut in half to get in the holes. Took me about an hour. I need to work on joining two wires and tinning.
Sorry for your troubles, lets go through each step and ensure we are doing the right set of thingsI have been struggling to just get my Pi board to boot up. I want to learn more about the Raspberry Pi and some rudimentary programming before I start in on my reefPi build. I don't know if I just have a bad board or what the deal is. I formatted a SD card and installed all of the files from the Noobs download on it, connected it to a monitor, keyboard, and mouse, powered it up and get nothing. The LED lights on the board so I know it is getting power, but nothing on the screen. I tried it by connecting up the 7" touchscreen as well and also nothing. Very frustrating. Is it possible that the Pi board itself is DOA? How should the SD card be formatted? Is a 64g card to big? Sorry for all of the very beginner level generic to the Pi questions, but I am extremely confused.
By the way, I use this solid core colored hookup wires to create jumpers (connect two different points in the perma proto board):Dave. I did noobs too. Formatted the card and then unzipped noobs and copied files. Lights come on. Did you hdmi to a monitor? One light comes on and other flickers like a drive read light I believe.

Just some questions about the repository. I've read the development documentation and check the files in the repo but some stuff seem strange to me. Why using "dependencies" with the package.json if you use ES6 and you compile it throught React? Everything will be bundled and you'll not have to rely on node_modules. Addition to this, the setup of all the procedure of all the installation can be done throught scripts trigger by "npm install" for example. It would be an improvement.
About Ui and React App i can help too if needed.
"Load test for reef-pi"
=> We can use Gherkin syntax and make a script to handle the scenarios you wanna try with a parallel context of multiples threads. The problem is i don't know how to get significant metrics on the raspberry for the load. I mean, i know how to do it on servers with watchers and storing data in Prometheus for example but in our case it will slow down the Pi too. Any idea? Or we just try the CRUD untill we get errors from the API ?
We would love to get any and all help on the development front. I am already getting some major help from @Michael Lane around form validation and making things nicer, responsive etc.Just some questions about the repository.

ES6 compiled single js file is used for packaging, thats the stuff that gets shipped to build or served by browser. dependencies and package.json is used to ensure reproducible developer environments. this is same as gemfile.lock or requirement.txt (ruby & python)
I have run telegraf (on pi) and grafana+influxdb(on a different pi) for gathering telemetry in past. If I do it now, probably go with Prometheus, but if its too heavy I may just right my own with gopsutil.
we can use pprofile as well. reef-pi is already integrated with go-pprofile, so you can extensive backend telemetry via /profile endpoint. You have to enable it from Configuration -> Settings-> Profile
I think a python client for the 2.0 API would be handy as well (or nodejs client).
Let me know if you need any help.
should be ok. check if its working . If the probe gets hot then you have wired it wrong. else it should be ok. its recommended to wire it against 5v if you have longer wire length between Pi and the ds18b20 probe@Ranjib I think I may have made a mistake on my DS18B20. I powered it thru the 5v side and not hte 3.3v side. will this make a difference?
